    Notes: Abstract The repeatability of the composition of pheromone emitted by individual female moths (Yponomeuta) was determined by gas Chromatographic analysis. An improved technique for repeated collections of airborne volatiles from the same moth was developed. The procedure did not harm the females and allowed precise quantification of 0.05 ng of pheromone components in 30-min collections. Individual females ofY. padellus (N=10) andY. rorellus (N=5) were sampled six and eight days after emergence.Y. padellus released, on average, 4.8 ng/30 min of tetradecyl acetate, (E)-11-tetradecenyl acetate, (Z)-11-tetradecenyl acetate, hexadecyl acetate, (Z)-9-hexadecenyl acetate, and (Z)-11-hexadecenyl acetate in the average ratio 445∶38∶100∶494∶35∶421. The amount of (E)-11-tetradecenyl acetate relative to (Z)-11-tetradecenyl acetate was less variable [coefficient of variation (CV)=15%] than the relative amounts of the other components (CV=46–61%). The repeatability of the relative amounts of compounds released by individual females was high for all components (r=0.82-0.90). The average emission of tetradecyl acetate, tetradecanol, hexadecyl acetate, and hexadecanol byY. rorellus was 8.3 ng/30 min (ratio 100∶8∶10∶2). The repeatability was low for tetradecanol (r=0.51) but higher for hexadecyl acetate (r=0.87) and hexadecanol (r=0.89). The low interindividual variance for the (E)-11-/(Z)-11-tetradecenyl acetate ratio inY. padellus might be due to its importance for reproductive isolation, i.e., it is under strong selection pressure.

    Four polymorphic markers on rat chromosome 12 form a single linkage group (1993)
    Springer
    Biochemical genetics 31 (1993), S. 441-448

    Notes: Abstract Four PCR-typable polymorphic markers were mapped to rat chromosome 12 by linkage analysis of F2 intercross progeny of Fischer (F344/N) and Lewis (LEW/N) rat strains. The markers formed a single linkage group, covering 27.7 cM, with the following order and distance between markers: plasminogen activator inhibitor (Planh)—0.0 cM—phosphoenolpyruvate carboxykinase-related sequence 2 (Pepckr2)—15.4 cM—anonymous marker (D12N155)—12.3 cM—serine dehydratase (Sdh). All markers were identified and genotyped by PCR analysis of simple sequence repeats. The gene encoding Planh was previously assigned to rat chromosome 12, which allowed us to assign the entire linkage group to this chromosome. These markers were highly polymorphic in 13 additional inbred rat strains (BUF/N, BN/SsN, WKY/N, MNR/N, LER/N, WBB1/N, WBB2/N, MR/N, LOU/MN, SHR/N, ACI/N, SR/Jr, and SS/Jr). These markers should be useful tools for further genetic studies in rats.

    Identification of new sex pheromone components inTrichoplusia ni, predicted from biosynthetic precursors (1984)

    Notes: Abstract In addition to the previously identified components (Z)-7-dodecenyl acetate and dodecyl acetate, sex pheromone glands ofTrichoplusia ni release (Z)-5-dodecenyl acetate, 11-dodecenyl acetate, (Z)-7-tetradecenyl acetate, and (Z)-9-tetradecenyl acetate. Bioassays in a flight tunnel showed that a synthetic blend of these six compounds elicited complete flights to the source from 95% of the males tested and elicited hairpenciling responses at the end of the flights from 88% of the males tested. This blend was not significantly different from intact pheromone glands, which elicited complete flights to the source from 98% of the males tested and hairpenciling responses from 91% of the males tested. In contrast, the previously identified two-component blend elicited significantly fewer complete flights to the source (33%) and did not elicit hairpenciling responses from any of the males tested. The search for additional sex pheromone components was prompted by our previous identification of unusual fatty acyl moieties in the gland that seemed to be possible biosynthetic intermediates.

    Redundancy in a chemical signal: Behavioral responses of maleTrichoplusia ni to a 6-Component sex pheromone blend (1984)

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The flight response of maleTrichoplusia ni was observed in a flight tunnel to a sex pheromone blend composed of six components:Z7–12∶Ac, 12∶Ac,Z5-12∶Ac, 11-12∶Ac,Z7-14∶Ac, and Z9-14∶Ac. The number of males reaching a 3000-μg source of this blend was 〉 95%, equal to that observed to female glands and significantly greater than with the previously identified two-component blend (Z7-12∶Ac + 12∶Ac). In subtraction tests, all five-component blends, with the exception of the blend lacking the primary componentZ7-12∶Ac, and several four-component blends elicited similar peak levels of upwind flight, source contacts, and hairpencil displays to that observed with the six-component blend. We characterize the substitution of certain minor components for one another as a form of redundancy in the chemical signal and suggest that it contributes to response specificity and signal recognition in males. The results also support the concept that the full blend of components acts as a unit to influence male behavior at all phases of the response. Individual minor components were not responsible for eliciting specific behaviors in the sequence.

    Notes: Abstract Pheromone blend analyses of glands from individual female European corn borers,Ostrinia nubilalis (Hübner), from field-collected larvae or pupae associated with bivoltine flights in June and August and a univoltine flight in July have shown that: (1) a site in western New York has a bivoltine biotype utilizing (Z)-11-tetradecenyl acetate as its primary pheromone component (designatedZ), (2) two sites in central New York have mixed populations consisting of a bivoltine biotype utilizing theE pheromone isomer (designatedE) and a univoltine biotype utilizingZ, and (3) one site in central New York was found to have only the univoltineZ biotype. The combinations of voltine biotypes and pheromone strains found in New York support the existence of three European corn borer populations designated bivoltineE, bivoltineZ, and univoltineZ.

    Notes: Abstract Three sex pheromone components of the carob moth were isolated and identified from the extract of female pheromone glands, using a variety of techniques including coupled gas chromatographic-electroantennographic recordings, coupled gas chromatographic-mass spectrometric analysis, microozonolysis, electroantennographic assays of monounsaturated standards, wind-tunnel bioassays, and field trials. The major component was identified as (Z,E)-9,11,13-tetradecatrienal, a novel lepidopterous pheromone component structure. Two minor components, either one of which improves the upwind flight response of males when blended with the major component, were identified as (Z,E)-9,11-tetradecadienal, and (Z)-9-tetra-decenal.
